OP, how long does it take you to go from empty to full charge? On our last trip we drove 605 miles home in one day. The beauty of diesel fuel is it only took one fill up to get home, which took a total of 15 minutes to get off the highway, fuel up, let the kids go to the bathroom, walk the dogs, make some sandwiches and get back on the highway.
Getting 150 miles per full charge would require starting full and then at least 3 stops. Driving up I95 on the east coast, you go through lots of rural areas and I can't image there are too many Tesla charging docks between larger towns.
